Scientific Cutting Tools SAEJ1926-08RA Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS SAEJ1926-08RA is a porting tool reamer designed for preparing hydraulic and fluid-system ports to SAE J1926, SAE J514, and MS 16142 standards. It produces a 1.198-inch spotface diameter with a 15-degree seal angle, creating the precise face geometry required for leak-free O-ring face seal (ORFS) and straight-thread port connections. The tool features 4 straight flutes with an AlTiN+ coating for extended tool life in steel and alloy workpieces. Shank diameter is 3/4 inch with an overall length of 3.7 inches. Licensed machinists, hydraulic system fabricators, and fluid-power technicians install this tool in machine shop or field porting operations.

This reamer is sized for 1/2-inch OD tube connections, corresponding to Tube Dash 8 fittings. It is used on hydraulic manifolds, valve bodies, cylinders, and fabricated fluid-power assemblies where SAE J1926 straight-thread ports or SAE J514 flareless tube fitting ports must be machined or reconditioned. The 0.688-inch minimum pilot diameter and 0.814-inch maximum pilot diameter allow the tool to self-locate in the bore, ensuring concentricity between the spotface and the threaded port. Typical applications include OEM fabrication and field repair of hydraulic and pneumatic systems in industrial and mobile equipment.

Key Features

• 1.198-inch spotface diameter machines the correct seating face for Dash 8 ORFS and straight-thread port fittings
• 15-degree seal angle conforms to SAE J1926, SAE J514, and MS 16142 port standards
• AlTiN+ coating improves hardness and heat resistance for extended service life in steel and alloy materials
• 4 straight flutes provide controlled chip evacuation during spotfacing and reaming operations
• Self-piloting design with 0.688-inch minimum and 0.814-inch maximum pilot diameter ensures bore concentricity
• 3/4-inch shank diameter compatible with standard drill press, mill, or hand-held porting tool drive systems

Compatibility

Designed for use on tube and port workpieces requiring Dash 8 (1/2-inch OD tube) straight-thread or flareless port preparation per SAE J1926, SAE J514, and MS 16142 standards. Thread type is UNF.

Installation Notes

This tool is operated by a machinist or trained hydraulic technician using a drill press, milling machine, or dedicated porting tool driver. Before machining, depressurize and de-energize the hydraulic or pneumatic circuit completely and secure the workpiece to prevent movement. Use appropriate cutting fluid for the workpiece material to protect the AlTiN+ coating and ensure proper finish. Verify port standards and fitting dash size before beginning any spotface operation to avoid undersizing or oversizing the seating surface.
